Question: Error uploading Galaxy file via HTTP

In our facility we have a web server that uploads files to Galaxy libraries via HTTP requests in PHP. It has been working for a while, but following an update to the latest version of Galaxy it started returning this error:

Fatal error: Exit code 1 ()
Traceback (most recent call last):
  File "/home/galaxy/galaxy/tools/data_source/", line 270, in <module>
  File "/home/galaxy/galaxy/tools/data_source/", line 263, in __main__
    metadata.append(add_file(dataset, registry, output_path))
  File "/home/galaxy/galaxy/tools/data_source/", line 136, in add_file
    if datatype.dataset_content_needs_grooming(dataset.path):
AttributeError: 'NoneType' object has no attribute 'dataset_content_needs_grooming'

If I comment out this section of the script, everything proceeds well and the files are usable by Galaxy, but it is not an ideal solution. Besides, those files do not have a known format.

This is the chunk of code that executes the POST request:

$params = array(
    'create_type' => 'file',
    'file_type' => 'auto',
    'dbkey' => '?',
    'folder_id' => $folder_id,
    'filesystem_paths' => $pathToFile,
    'link_data_only' => "link_to_files",
    'upload_option' => "upload_paths",
 $URL = $baseURL . '/api/libraries/' . $library_id . '/contents/?key=' . $adminAPI;
$responseLibrary = httpPOST($URL, $params); // Send POST request

Interestingly, everything works as intended if I use bioblend. Any ideas on what might be wrong? At first I thought that 'file_type' might be necessary and I added it, to no avail...

What is the bioblend analog you're using? I haven't had to work with PHP in some time, I'll look and see what might be happening with the payload on post.

Hi, thanks for the reply. I am using the following in bioblend:

gi = GalaxyInstance(url = GALAXY_URL, key=key_admin)

As I said, this works fine. In PHP, the file is sent to the library (the POST request is successful), but the upload process fails at the lines mentioned above. As a result, it's shown with the state "error" and it has no data type.
